TECHNICAL FIELD

The present disclosure relates to the technical field of rail transit, in particular to a submerged floating rail transit system.

BACKGROUND ART

The ocean area on the earth accounts for 71%, and even more than three quarters if the area of lakes and rivers is added. In order to move on the earth surface, human beings cut a road when confronted by mountains, build a bridge when confronted by rivers, dig tunnels and build high-speed railways; in order to move on the water, various ships are invented. However, generally speaking, because human activities are concentrated on land, most of the traffic focuses on land. Water surface, such as oceans, lakes and rivers, is still the biggest factor hindering traffic.

In order to facilitate water transportation, subsea tunnels and cross-sea bridges have been built, such as the English Channel subsea tunnel in Europe, the Hangzhou Bay Cross-sea Bridge in China and the Guangdong-Hong Kong-Macao Cross-sea Bridge in the Pearl River Estuary. The water surface will be transformed into hard ground through tunnel bridges to realize convenient transportation. In recent years, the Bohai Bay Cross-sea Tunnel has aroused extensive heated discussion, and Qiongzhou Strait, which connects Hainan, is still in the debate of whether it is a bridge or a tunnel.

Whether a bridge is built on the water surface or a tunnel is excavated under the water, it is a huge investment project, which cannot give full play to the advantages of the water surface. The advantage of water surface is buoyancy, and shipping is the lowest cost mode of transportation. However, due to the limitation of speed, shipping is not the most efficient. This is because the propeller pushes the water forward so as to push ships to move, but from the perspective of momentum conservation, in order to push the ship forward, it is necessary to apply force and water through the propeller, and water flows under the action of thrust because it is a fluid. Therefore, according to the law of conservation of energy, the forward movement of ships will inevitably lead to backward flow of water, which is not an efficient way of energy utilization. Human beings have also tried this, such as the rope crossing the river, the ferryman stepping on the boat and pulling the rope with his hand, such as supporting the boat with bamboo poles in shallow water, and letting the boatman pull the boat with the rope on the river bank, etc., but all of which have the problem of low efficiency.
